AWS healthlake documentation change

Service: healthlake · 2025-08-25 · Documentation low

File: healthlake/latest/devguide/releases.md

Summary

Added documentation for new FHIR operations ($validate, $lookup, $expand) and search modifier

Security assessment

Documents new functionality rather than addressing security issues. $validate operation improves data quality but isn't explicitly a security feature.
